UNITED STATES RICHARD E. HUNKE CHARLIE H. OMF WAGO,

CMBINATION JIG .AND VISE.

Application filed July 28, 1923.

To all whom/@'15 may concern Be it known that we, RICHARD E. Homin andCHARLIE H. FRANK, citizens of the United States, and residents of Waco,in the county of McLennan and State of Texas. have invented certain newand useful lmprovements in Combination Jigs and Vises; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The present invention relates to combination jig and vise and will befound particularly useful in conjunction with work upon the pistons ofinternal combustion engines.

An object of the invention is to provide a simple and compactconstruction admitting of a variety of adjustments in the vise or holderand in the tool guide; and the invention further contemplates theconvenience of the workmen and the quickness and efliciency in the work.

With the foregoing and other objects in view, the invention will hejmore fully described hereinafter, and will be more particularly pointedout in the claims appended hereto.

In the drawings, wherein like symbols refer to like or correspondingparts throughout the several views,

Figure 1 is a side elevation of a device constructed according to thepresent invention.

Figure 2 is a top plan view thereof.

Figure 3 is a longitudinal section taken on the line 3 3 in Figure 2,and

Figure 4 is a transverse section taken centrally through the device.

Referring more particularly to the drawings 5 designates a. bed or baseplate upon which the various parts are installed and erected and nearone end are the blocks or bearing 6 to receive the shaft or trunnions 7on which is pivotally mounted the vise table or block 8. This table orblock is formed with separate transverse dove-tail grooves 9 and 10 toreceive the complementally formed projections 11 and 12 eX- tendingdownwardly from the two jaws 13. These jaws have rounded depressions 14as shown in Figure 4 in4 order to receive the jaw faces 15. The jawfaces 15 may be of any suitable character and are removably attached tothe jaws to enable the substitu- Gerial No. 654,449.

tion of jaw faces to suit the character of the work to be performed.

In the present case the jaw faces are shown as rounded to receive apiston. The jaws 1?) are adjustable toward and from 60 each other by ascrew shaft 16 passing centrally through the aws and being fixedccntrally in a bearing 17 which prevents the shaft from moving axiallybut freely admits of its turning. The shaft is provided with threads ofopposite pitch in order to cause the jaws to move apart when the shaftis turned in one direction and to approach one another upon the rotationof the shaft in the opposite direction.

The vise table 8 is provided with a leg 18 pivoted beneath the free endof the table as indicated at 19 and either having its op posits end freeor pivoted to the sliding block 20 mounted forv movement in a central 75groove 21 made in the bed 5. yl`l1e block 20 is provided with a setscrew 22 by which its location may be fixed. rlhe groove 21 as shown inFigure 4 is a dove-tail groove and the tightening of the screw 22 causes30 the binding of the wedge-shape block 20 in the walls of said groove.

The bed plate shown in Figure 2 is provided with lugs 23 extendinglaterally therefrom in pairs to receive rods 24 forming sup- 35 portsfor 'the sliding heads 25 having` set screws 26 by which the heads maybe secured against movement once the adjust ment is effected. The headsare provided with posts 27 extending upwardly and pro- 90 vided withthreads to receive pairs of nuts 2S and 29. The nuts serve to supportthe guide bar 30 which extends across from one post to the other. Thebar is provided with perforations to slide on the posts being J5supported by the lower nut 29 and held rigidlv in place by the upper nut28.

In the use of the device the jaws 13 are first made to open sufficientlyto receive for instance a pistonhaving a broken wrist pin. rlhe jaws arethereupon moved together to clamp the piston in place and the vise tableis adjusted angularly as shown in Figure 3 to a suitable position forbringing the piston and its broken wrist pin into a correct relativeposition with respect to the guide bar `550. Appropriate tools are thenemployed to remove the broken wrist pin and to perform other necessarywork on the piston. The vise .table may be adjusted to any anguiarposition or may be laid flat on the bed and the tool and guide bar willbe adjusted asto elevation and also longitudinally along the rods 24 asrequired.

The guide bar 3() is provided with a guide thimble 301 for receiving adrill. The thimble will guide the drill bit in its operation. The bar 30is a support tor the bit guide 301 and is adjustable horizontally and asto height in order to bringthe thimble ()l to a correct position withreference to the Work Where it may guide the drill.

It will be appreciated from the foregoing that the device is compact andadmits oi a variety of positions which add tothe eonvenience andeffectiveness oi'' the workmen in this character of work.

It is obvious that various changes and modilications may be made in thedetails of construction and desi-gn of the above speciti- Y callydescribed embodiment of this invention Without departing trom the spiritthereof, such changes and modifications beingfre- 'stricted only by thescope of the following claims.

that is claimed is 1. A combination jig andvise comprising a bed, a visetable hinged at one end to the bed, a hinged leg :tor holding the treeend of the vise table in angularly adjusted position, and an adjustableguide bar carried by the bed and movable relatively to said vise table.

2. A combination jig andA vise comprising a bed, a vise table pivotedthereto, a leg pivotally carried by the free end of said vise table, andengaging the bed at a successive number of points to hold the table inangularly adjusted position, means on said table for releasably graspingthe work, and an adjustable guide bar mounted on said table.

3. A combination and vise comprising a bed, a vise table hinged thereto,means for adjustably holding saidtable at dilierent 'angular positions,means on'said table for releasably holding the work, adjustable postsmovable along the bed at the sides of said vise table, and a guide barcarried by said posts.

Ll. A combination and vise comprising a bed, a vise table pivotedthereto, means for holding said table in a variety ot angular positionsabout the pivotal point, means carried by said vise table tor releasablyholding the work, posts slidable alongside said bed, means tor securingsaid posts in adjusted position., and a guide bar adjustably carried bysaid posts.

A combination and vise comprising `a bed having a groove therein, a visetable hinged thereto, a leg pivoted to the :tree end ol the table, ablock slidable in said groove, the leg being also pivoted to the block,vise jaws carried by said table, and a guide bar adj ustably mounted inconjunction with said vise table.

6. A combination jig and vise comprising a bed, having a longitudinaland substantially central groove, a vise table pivoted at one end ot thebed, a hinged leg carried by the free end of said table, a block securedto the other end ot said leg slidably fitted in the groove in said bed,means for securing the bloei; irictionally against movement, and a guidebar adjustable relatively to said table.

7. A combination and vise comprising a bed, a table pivoted thereon andhaving separated tansverse dovetail grooves, jaws having projectionsslidably fitted in said grooves, means Vtor causing the aws to moveapart and approach each other, jaw faces carried removably by said jaws,means tor tilting the table, bars carried at the sides ot said bedplate, posts having sleeves slidable on said bars, a guide bar fittedover said posts, and adjustable nuts on the posts above and below thebars tor regulating the height thereof.
